On a second attempt, the error refuses to show itself. I tried both with and without the change to /usr/share/libvirt/cpu_map/x86_features.xml and it made no difference. I can only assume it's because I rebooted after some system updates (though these were not to qemu or libvirt directly). Now on kernel 4.19.13-300.fc29.x86_64 if it matters.
Sorry for the noise. I'll come back to this if it happens again.
